Free travel companion for food allergies
The restaurant allergy card that speaks 24 languages, even offline
Ordering with a food allergy in a country whose language you do not speak is stressful. TrustBite builds a clear allergy card from your own profile and shows it to restaurant staff in their language, from Thai and Japanese to Chinese and Arabic. It works with no signal, so you are covered on a mountain road or a rural trattoria. Free to use, with a barcode scanner and AI menu scan built in.
What a restaurant allergy card actually is
A restaurant allergy card is a short, unambiguous message that names exactly which foods you must avoid, written in the language the kitchen reads. Instead of miming or hoping a waiter understands broken phrases, you hand over your phone and let the card do the talking. TrustBite generates yours automatically from the allergens you select, so the wording is consistent, complete and never lost in translation. Each card states your allergens plainly and asks the kitchen to keep your meal free of them, in a tone staff can act on right away.
How to use it abroad, step by step
Set up your profile once: tap the 14 EU allergens that apply to you and choose how severe each one is. When you sit down, open the card and pick the local language from the 24 on offer. Show your screen to the waiter or kitchen, or let them read it at the counter. Because everything is stored on your device, you do not need roaming data or Wi‑Fi, the card opens instantly in a basement restaurant, on a ferry, or deep in the countryside. You can keep separate profiles for a partner or child and switch between them in a tap.
24 languages, 14 allergens, and an emergency contact
The card covers 24 languages including Thai, Japanese, Chinese and Arabic, so scripts that are hard to write by hand are handled for you. All 14 EU‑labelled allergens are supported, gluten, peanut, tree nut, milk, egg, fish, shellfish, soy, sesame, mustard, celery, sulphite, lupin and mollusc, each shown with the severity you set so staff grasp what is a strict must‑avoid. You can also store an ICE emergency contact on the card, so if something does go wrong, the people around you know who to call. Beyond the card, scan barcodes against Open Food Facts for a green, yellow or red verdict, and photograph a menu to have the AI flag risky dishes.

Is TrustBite free?
Yes, the allergy card, the barcode scanner and the core features are free. There is an optional Pro upgrade for heavier use, but you can build and show your card and keep an ICE contact without paying anything.
Can I rely on the card instead of talking to staff?
No. TrustBite is an aid, not a medical device, and it does not guarantee a meal is safe. Always confirm with restaurant staff before you eat, and if you have a severe reaction, call your local emergency number or 112 in the EU.
